The genpd framework allows users to add PM domains via the pm_genpd_init() function, however, there is no corresponding function to remove a PM domain. For most devices this may be fine as the PM domains are never removed, however, for devices that wish to populate the PM domains from within a driver, having the ability to remove a PM domain if the probing of the device fails or the driver is unloaded is necessary. Add the function pm_genpd_remove() to remove a PM domain by referencing it's generic_pm_domain structure. Note that the bulk of the code that removes the PM domain is placed in a separate local function genpd_remove() (which is called by pm_genpd_remove()). The code is structured in this way to prepare for adding another function to remove a PM domain by provider that will also call genpd_remove(). Note that users of genpd_remove() must call this function with the mutex, gpd_list_lock, held. PM domains can only be removed if the associated provider has been removed, they are not a parent domain to another PM domain and have no devices associated with them.

It is possible that a device has more than one provider of PM domains and to support the removal of a PM domain by provider, it is necessary to store a reference to the provider in the PM domain structure. Therefore, store a reference to the firmware node handle in the PM domain structure and populate it when providers (only device-tree based providers are currently supported by PM domains) are registered. Please note that when removing PM domains, it is necessary to verify that the PM domain provider has been removed from the list of providers before the PM domain can be removed. To do this add another member to the PM domain structure that indicates if the provider is present and set this member accordingly when providers are added and removed. Initialise the 'provider' and 'has_provider' members of the generic_pm_domain structure when a PM domains is added by calling pm_genpd_init().

In order to remove PM domains safely from the list of PM domains, it is necessary to adding locking for the PM domain list around any places where devices or subdomains are added to a PM domain. There are places where a reference to a PM domain is obtained via calling of_genpd_get_from_provider() before adding the device or the subdomain. In these cases a lock for the PM domain list needs to be held around the call to of_genpd_get_from_provider() and the call to add the device/subdomain. To avoid deadlocks by multiple attempts to obtain the PM domain list lock, add functions genpd_add_device() and genpd_add_subdomain() which require the user to hold the PM domain list lock when calling.

When a PM domain provider is added, there is currently no way to tell if any PM domains associated with the provider are present. Naturally, the PM domain provider should not be registered if the PM domains have not been added. Nonetheless, verify that the PM domain(s) associated with a provider are present when registering the PM domain provider. This change adds a dependency on the function pm_genpd_present() when CONFIG_PM_GENERIC_DOMAINS_OF is enabled and so ensure this function is available when CONFIG_PM_GENERIC_DOMAINS_OF selected.

Functions __of_genpd_xlate_simple(), __of_genpd_xlate_onecell() and __of_genpd_add_provider() are not used outside of the core generic PM domain code. Therefore, reduce the number of APIs exposed by making these static. At the same time don't expose the typedef for genpd_xlate_t either and make this a local definition as well. The functions are renamed to follow the naming conventions for static functions in the generic PM domain core.

There should be no need to expose the generic_pm_domain structure to clients and this eliminates the need to implement reference counting for any external reference to a PM domain. Therefore, make the functions pm_genpd_lookup_dev() and of_genpd_get_from_provider() private to the PM domain core.

Ideally, if we are returning a reference to a PM domain via a call to of_genpd_get_from_provider(), then we should keep track of such references via a reference count. The reference count could then be used to determine if a PM domain can be safely removed. Alternatively, it is possible to avoid such external references by providing APIs to access the PM domain and hence, eliminate any calls to of_genpd_get_from_provider(). Add new helper functions for adding a device and a subdomain to a PM domain when using device-tree, so that external calls to of_genpd_get_from_provider() can be removed.

Debugfs support for PM domains is only enabled if both CONFIG_PM_DEBUG and CONFIG_PM_ADVANCED_DEBUG are enabled. CONFIG_PM_ADVANCED_DEBUG is described as "extra PM attributes in sysfs for low-level debugging/testing" which does not seem related. Given that the debugfs for PM domains only allows users to view the state of the PM domains, always enable debugfs support for PM domains if PM domains and debugfs support is enabled.

Since commit 63a4cc24, bio->bi_rw contains flags in the lower portion and the op code in the higher portions. This means that old code that relies on manually setting bi_rw is most likely going to be broken. Instead of letting that brokeness linger, rename the member, to force old and out-of-tree code to break at compile time instead of at runtime. No intended functional changes in this commit.

Commit abf54548 changed it from an 'rw' flags type to the newer ops based interface, but now we're effectively leaking some bdev internals to the rest of the kernel. Since we only care about whether it's a read or a write at that level, just pass in a bool 'is_write' parameter instead. Then we can also move op_is_write() and friends back under CONFIG_BLOCK protection. Reviewed-by: NMike Christie <mchristi@redhat.com> Signed-off-by: NJens Axboe <axboe@fb.com>

Merge tag 'xfs-rmap-for-linus-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs Pull more xfs updates from Dave Chinner: "This is the second part of the XFS updates for this merge cycle, and contains the new reverse block mapping feature for XFS. Reverse mapping allows us to track the owner of a specific block on disk precisely. It is implemented as a set of btrees (one per allocation group) that track the owners of allocated extents. Effectively it is a "used space tree" that is updated when we allocate or free extents. i.e. it is coherent with the free space btrees we already maintain and never overlaps with them. This reverse mapping infrastructure is the building block of several upcoming features - reflink, copy-on-write data, dedupe, online metadata and data scrubbing, highly accurate bad sector/data loss reporting to users, and significantly improved reconstruction of damaged and corrupted filesystems. There's a lot of new stuff coming along in the next couple of cycles,a nd it all builds in the rmap infrastructure. As such, it's a huge chunk of new code with new on-disk format features and internal infrastructure. It warns at mount time as an experimental feature and that it may eat data (as we do with all new on-disk features until they stabilise). We have not released userspace suport for it yet - userspace support currently requires download from Darrick's xfsprogs repo and build from source, so the access to this feature is really developer/tester only at this point. Initial userspace support will be released at the same time kernel with this code in it is released. The new rmap enabled code regresses 3 xfstests - all are ENOSPC related corner cases, one of which Darrick posted a fix for a few hours ago. The other two are fixed by infrastructure that is part of the upcoming reflink patchset. This new ENOSPC infrastructure requires a on-disk format tweak required to keep mount times in check - we need to keep an on-disk count of allocated rmapbt blocks so we don't have to scan the entire btrees at mount time to count them.

Pull block fixes from Jens Axboe: "Here's the second round of block updates for this merge window. It's a mix of fixes for changes that went in previously in this round, and fixes in general. This pull request contains: - Fixes for loop from Christoph - A bdi vs gendisk lifetime fix from Dan, worth two cookies. - A blk-mq timeout fix, when on frozen queues. From Gabriel. - Writeback fix from Jan, ensuring that __writeback_single_inode() does the right thing. - Fix for bio->bi_rw usage in f2fs from me. - Error path deadlock fix in blk-mq sysfs registration from me. - Floppy O_ACCMODE fix from Jiri. - Fix to the new bio op methods from Mike. One more followup will be coming here, ensuring that we don't propagate the block types outside of block. That, and a rename of bio->bi_rw is coming right after -rc1 is cut. - Various little fixes" * 'for-linus' of git://git.kernel.dk/linux-block: mm/block: convert rw_page users to bio op use loop: make do_req_filebacked more robust loop: don't try to use AIO for discards blk-mq: fix deadlock in blk_mq_register_disk() error path Include: blkdev: Removed duplicate 'struct request;' declaration.

Pull more ACPI updates from Rafael Wysocki: "Two more fixes in ACPI drivers, one in the ACPI EC driver (stable-candidate) and one in the ACPI button driver. Specifics: - An ACPI EC driver fix from the 4.3 cycle may cause the ACPICA's method reentrancy limit to be exceeded for a _Qxx method due to a large number of concurrent EC operations, so prevent that from happening by moving the EC handling into a separate workqueue with a limit on the number of concurrently executed work items (Lv Zheng) - Fix the cleanup code in the ACPI button driver that forgets to clear two variables on exit which causes an error to occur on the next attmpt to load the driver (Benjamin Tissoires)" * tag 'acpi-extra-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / EC: Work around method reentrancy limit in ACPICA for _Qxx ACPI / button: remove pointer to old lid_sysfs on unbind

Pull more power management updates from Rafael Wysocki: "A few more fixes and cleanups in the x86-64 low-level hibernation code, PM core, cpufreq (Kconfig and intel_pstate), and the operating points framework. Specifics: - Prevent the low-level assembly hibernate code on x86-64 from referring to __PAGE_OFFSET directly as a symbol which doesn't work when the kernel identity mapping base is randomized, in which case __PAGE_OFFSET is a variable (Rafael Wysocki). - Avoid selecting CPU_FREQ_STAT by default as the statistics are not required for proper cpufreq operation (Borislav Petkov). - Add Skylake-X and Broadwell-X IDs to the intel_pstate's list of processors where out-of-band (OBB) control of P-states is possible and if that is in use, intel_pstate should not attempt to manage P-states (Srinivas Pandruvada). - Drop some unnecessary checks from the wakeup IRQ handling code in the PM core (Markus Elfring). - Reduce the number operating performance point (OPP) lookups in one of the OPP framework's helper functions (Jisheng Zhang)" * tag 'pm-extra-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: x86/power/64: Do not refer to __PAGE_OFFSET from assembly code cpufreq: Do not default-yes CPU_FREQ_STAT cpufreq: intel_pstate: Add more out-of-band IDs PM / OPP: optimize dev_pm_opp_set_rate() performance a bit PM-wakeup: Delete unnecessary checks before three function calls
